Messages & Announcements

Maintenance being conducted on the fiber ring between Lincoln and Omaha is impacting network connectivity to and between HCC's data centers. The maintenance is ongoing with no known ETA.

This affects external connections to HCC's PKI datacenter (TUSKER/CRANE/ANVIL/ATTIC) and the use of the /common filesystem on SANDHILLS. Internal networking at HCC data centers is functioning and running jobs should remain unaffected unless they depend on external data sources.

This maintenance which began yesterday was not intended to be disruptive but is causing significant disruption to our network connectivity. Feel free to try and use HCC resources during this time, but expect network interruptions such as stalled SSH sessions until it is resolved.

This work is completely outside the control of HCC staff, and we cannot provide any ETA on when the work will be completed.

SANDHILLS experienced prolonged power outage last night between ~3:30am-~5:30am. Battery backup systems did not provide enough buffer and several key systems powered down including $WORK infrastructure and LDAP. SANDHILLS is currently functional but fragile. You will probably have to restart your jobs. Please report any issues to hcc-support@unl.edu.
